The diaphragm wall was originally used in the hydraulic engineering, and later extended to other high-rise building foundation and underground Metro, with the new equipment and construction process of continuous innovation. In recent years, several large-scale suspension bridges adopted diaphragm walls as the supports. Combing with the practice of several large suspension bridge engineering, this paper describes the construction technology of the diaphragm wall and based on the anchorage underground continuous wall construction techniques are introduced and analyzed, and from the perspective of its technology and management quality control measures.
